The favourite bar should allow me to change the current running time to one of my favourite options as well as the current logic which stops the current timer and starts a new time entry.
Often I start a timer before deciding exactly what task I want to move onto and I should be able to use the favourites bar in this situation as well as just when I want to switch task.
Using the favourites bar in this situation just leaves me with small unallocated time that I have to clear up later.
